    摘要： A protocol and apparatus for crossbar switches where the cycle time is too short to allow the updating of the input/output buffer controls by the arbitration logic in one cycle. The crossbar switch has separate data paths and commands paths. Two types of commands are sent over the crossbar switches. The first type is an address (A) only command which consist of a single packet needing one clock cycle. The second type of command is an Address with Data command (AD), consisting of two through nine packets, and requiring a maximum of nine clock cycles. A command becomes a request through two different paths through the crossbar switch. The first path is via an input bypass path which allows an input command buffer to be bypassed and a request written directly to a multiplexer. The second path is through the input command buffer which is written but not selected until processing is completed for the previous command. The crossbar protocol allows a request to be accepted by writing information into the output buffers before the accept is available.

    摘要： A system for handling denormal floating point operands when the result must be normalized. A leading zero counter (lzc) on the operand B (opB) is used to limit alignment shifts when opB is denormal but is much greater than the product of operands A and C, i.e. AC. By limiting the additional shift of B during normalization, by the number of leading zeros in opB, no increase is needed in the output bus of the alignment shifter. Furthermore, the additional shift may be done either in the alignment shifter, or postponed to a later stage in the pipeline, where the result is normalized.

    摘要： Disclosed is an apparatus incorporating hardware based logic and a predetermined default list of software affecting responses to be taken in connection with temperatures sensed by thermal sensors checking the temperature of portions of computer logic. At the time application software is loaded, the software can modify the default response list. The list of responses to be taken and the over temperature conditions at which they are to be activated are stored in hardware directly accessible by hardware based thermal sensor monitoring logic for direct control of the hardware. The control can alter conditions such as clock frequency, stopping use of application software, interrupting OS functionality, removing power from components and so forth.
